Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2015.

flex-shrink CSS property는 flex-item 요소의 flex-shrink 값을 설정하는 속성입니다. 만약 flex-item 요소의 크기가 flex-container 요소의 크기보다 클 때 flex-shrink 속성을 사용하는데, 설정된 숫자값에 따라 flex-container 요소 내부에서 flex-item 요소의 크기가 축소됩니다.
